My windshield washer doesn't work very well, there is almost no pressure when the fluid comes out. As you can see in the photo below, there is a section of clear tube which I added a while back due to a rupture in the original black tube.
Now there seems to be another rupture in a different spot on the black tube so I plan on just replacing it (the black tube is #1 in the photo).
My question is, do I need to replace #2 and/or #3 in order to replace #1? What are these parts called so I can ask for them?
I don't think it matters, but this is on a 2003 Infiniti g35.
